Final answer:
The word root of 'verbatim' is 'verb', and for 'impossible', it is 'poss'. Understanding the structure includes identifying prefixes, roots, and suffixes. Palatalization can influence spelling, as seen in 'spiritual'.
Step-by-step explanation:
The word root in verbatim is 'verb'. The Latin root 'verb' means 'word' and it's at the front of 'verbatim', which signifies the manner of 'in exactly the same words'. For the word impossible, the root is 'poss', derived from 'posse', which means 'to be able' in Latin. 'Im' is the prefix that negates the root, meaning 'not possible'.
Analyze each word by identifying the free stem and any suffixes. For example, with impossible, the im- is the prefix, poss is the free stem, and -ible is the suffix. If there were any final es deleted in the word formation, they should be replaced before analysis.
For the exercise involving combining prefixes, bases, and suffixes, one should look for instances of palatalization where [ch] is spelled 't'. An example is spiritual where the [t] results from palatalization of the base 'spirit' and the suffix 'ual'. This does not always happen, so it is essential to recognize when dis + gest + ion becomes 'digestion', 'question + er' becomes 'questioner', 'act + ual + ly' becomes 'actually', 'ad + vent + ure + ous' becomes 'adventurous', 'script + ure + al' becomes 'scriptural', and 'liter + ate + ure' becomes 'literature'.
